| bacteroidales ectosymbionts of gut flagellates shape the nitrogen-fixing community in dry-wood termites. | although it is well documented that the lack of nitrogen in the diet of wood-feeding termites is compensated by the nitrogen-fixing capacity of their gut microbiota, the bacteria responsible for this activity are largely unknown. here, we analyzed the diversity and expression of nitrogenase genes (homologs of nifh) in four species of dry-wood termites (kalotermitidae), which thrive on a particularly nitrogen-poor resource. although each species harbored a highly diverse suite of termite-specific ... | 2011 | 22189498 |
| molecular phylogeny of parabasalids inferred from small subunit rrna sequences, with emphasis on the devescovinidae and calonymphidae (trichomonadea). | small subunit rrna sequences were obtained by polymerase chain reaction from trichomonad symbionts of termites that belong to the polymastigont calonymphidae, including snyderella tabogae, calonympha grassii, and metacoronympha senta. the yet-unidentified sequence nk9 previously obtained from the termite neotermes koshunensis, has also been shown to derive from the devescovinidae devescovina sp. by in situ hybridization. these new sequences were analyzed by distance, parsimony, and likelihood me ... | 2002 | 12450758 |
| dna fluorescent stain accumulates in the golgi but not in the kinetosomes of amitochondriate protists. | hindgut symbiotic trichomonads (uninucleate caduceia versatilis, and multinucleate stephanonympha sp. and snyderella tabogae) from the dry-wood-eating termite cryptotermes cavifrons (kalotermitidae) accumulate dapi (4,6diamidino-2-phenylindole) in the membranous sacs of the golgi complex. this form of golgi complex, typical of protists in the class parabasalia, is called a parabasal body. trichomonads contain organellar systems, mastigonts, that consist of four undulipodia (e.g. eukaryotic flage ... | 2000 | 10963333 |
